WATERPROOFING COMPOSITION AND METHOD OF MAKING THE SAME.

Ho Drawing.

To all whom it may concern:

Be it known that I, GEORGE W. KRAMER, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented a new and useful Improvement in Waterproofin Compositions and Methods of Making t e Same, of

. which the following is a specification.

This invention relates to improvements in composition of matter and method of making the same, and to a com osition of matter more especially adapted or use as a paint or filler to render the surface to which it isapplied waterproof. It is adapted for i use on pasteboard, cardboard, paper, cement,

concrete, stone, masonry, brick, wood, plaster and other surfaces whether porous or not. It fills the pores of any surface to which it is a plied, and renders the same waterproof. t also serves to prevent the formation of alkali bloom on cement, concrete, stone and masonry surfaces; and has the effect of removing such alkali bloom from such surfaces when applied. The substance is also substantially transparent which is n advantage since its presence is not readily noticeable; and a covering of it on a surface does not materially alter the original appearance of the surface. g, It may be applied to colored bricks, colored stones and the like, without substantially covering the color or altering the appearance of the surface to which it is applied. These statements, of course, apply'to the composition of matter when made without coloring matter therein. As will be explained more in detail, hereinafter, the composition of matter may also have a coloring matter added to give it a color if desired.

I will now describe in detail the ingre dients from which my improved composition of matter is made, and the manner in which they are compounded. In doing this I am giving what I have found to be one successful method of making the composition of matter.

It is obviou however that, without de tracting from the spirit of my invention, changes in the proportions of the ingredients and the manner of compoundin the same may be made. Also, in all probability, certain components may be omitted entirely, and substitutions of equivalents or substantial equivalents may be made. The particu- Application filed August 31, 1921. Serial No. 497,882.

lar method which I have found to be successful is as follows: I take six pounds of parafline and .four pounds of red oil (oleic acid), heat them until they melt and then stir them together. I then add ten pounds of thinner, such as turpentine, gasoline and the like, and stir the mixture thoroughly, maintaining just enou h heat to keep the composition from soli ifyin I then let the temperature drop, but whi e the com osition is still in a liquid state I add a ut twenty pounds of 3 F. or 4 F. ammonia (26 to 29 Baum) and stir rapidly for about fifteen minutes; During this stirring the composition turns into a heavy syrup and saponification takes places. I then add water equal to about one-half the volume of the composition and stir the mixture. I then take about five pounds of aluminum sulphate, dissolve the same in water and then add this solution of aluminum sulphate to the mixtureiand stir the same in. I then add about two pounds of dilute hydrochloric acid. The resulting composition is a white thin flu'id resembling milk in appearance, and is apparently an emulsion of parafline. If it is desired to color the composition any suitable oil soluble color may be added. I

have found it preferable to add the color-- ing just before or just after adding the ammonia.

I do not know exactly what the chemical actions or reaction are which take lace in the making of my composition. Ila seems however that the ammonia with the parafline and oleic acid causes saponification which effects an emulsification of the melted paraffine. Although in describing a particular method above, I have stated that the thinner, such as turpentine or gasoline, is added before the ammonia; it is obvious that, without detracting from the spirit of this invention, such thinner may be added at other stages in the process. For-example, it could be added after the saponification takes Likewise, the parafiine or wax cou d be added after the ammonia. In other words, the ammonia and oleic acid could be mixed to cause saponification, and the arafline or wax could then be added to this resulting aqueous soap solution, and the mixture heated to melt the wax. After this the aluminum' sulphate,- or other metal salt, could be lace.

added to react on the soap solution to form and precipitate a substantially water insol- 'uble metal soapor metal salt. It would seem also that, without detracting fromthe spirit of my invention, any other suitable alkali which would effect the desired saponification could be substituted for the ammonia; and that also equivalents for the oleic acid and possibly the paraiiine wax cbuld be used which would perform substantiallly t the same functions as these substances.

seems also that the aluminum sulphate forms an insoluble aluminum soa product, probably aluminum oleate, and t at, without detracting from the spirit of my invention, any other metal salt which would give substantially the same result could be substituted for the aluminum sulphate. The

turpentine acts as a carrier or thinner and assists in making the composition of matter permeate the smallest pores in the surface to which applied. 'After application the turpentine evaporates leaving the remaining substances hardened. The parafiine dries and hardens and forms the basis of the permanent coat. It is obvious that, without detracting from the spirit of my invention, other waxes and other similar substances may be used in place of the parafline. The hydrochloric acid is added merely for the purpose of giving a mild acid to assist in removing dirt. It is not at all essential to the composition.

While I have shown and described certain embodiments of my invention, it i to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement maybe made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invfention as broadly as possible in view of the prior art.
